TORY funding cuts will force English schools to sack staff and pack more pupils into every classroom, according to an alarming independent analysis revealed yesterday.

The House of Commons Library has forecast a “real terms cut in per pupil funding” that will leave schools £7.5 billion short by 2020.

English schools are already facing the biggest budget cuts since the last all-Tory government in the mid-1990s, the Institute for Fiscal Studies warned.
